\subsection{\-Detailed \-Description}
\-The {\itshape sysclk\/} \-A\-P\-I covers the {\itshape system clock\/} and all clocks derived from it. \-The system clock is a chip-\/internal clock on which all {\itshape synchronous clocks\/}, i.\-e. \-C\-P\-U and bus/peripheral clocks, are based. \-The system clock is typically generated from one of a variety of sources, which may include crystal and \-R\-C oscillators as well as \-P\-L\-Ls. \-The clocks derived from the system clock are sometimes also known as {\itshape synchronous clocks\/}, since they always run synchronously with respect to each other, as opposed to {\itshape generic clocks\/} which may run from different oscillators or \-P\-L\-Ls.

\-Most applications should simply call \hyperlink{group__sysclk__group_ga242399e48a97739c88b4d0c00f6101de}{sysclk\-\_\-init()} to initialize everything related to the system clock and its source (oscillator, \-P\-L\-L or \-D\-F\-L\-L), and leave it at that. \-More advanced applications, and platform-\/specific drivers, may require additional services from the clock system, some of which may be platform-\/specific.\hypertarget{group__sysclk__group_sysclk_group_platform}{}\subsection{\-Platform Dependencies}\label{group__sysclk__group_sysclk_group_platform}
\-The sysclk \-A\-P\-I is partially chip-\/ or platform-\/specific. \-While all platforms provide mostly the same functionality, there are some variations around how different bus types and clock tree structures are handled.

\-The following functions are available on all platforms with the same parameters and functionality. \-These functions may be called freely by portable applications, drivers and services\-:
\begin{DoxyItemize}
\item \hyperlink{group__sysclk__group_ga242399e48a97739c88b4d0c00f6101de}{sysclk\-\_\-init()}
\item \hyperlink{group__sysclk__group_ga222a121dfaac21b0c0af9d4dcb39496c}{sysclk\-\_\-set\-\_\-source()}
\item sysclk\-\_\-get\-\_\-main\-\_\-hz()
\item sysclk\-\_\-get\-\_\-cpu\-\_\-hz()
\item sysclk\-\_\-get\-\_\-peripheral\-\_\-bus\-\_\-hz()
\end{DoxyItemize}

\-The following functions are available on all platforms, but there may be variations in the function signature (i.\-e. parameters) and behaviour. \-These functions are typically called by platform-\/specific parts of drivers, and applications that aren't intended to be portable\-:
\begin{DoxyItemize}
\item sysclk\-\_\-enable\-\_\-peripheral\-\_\-clock()
\item sysclk\-\_\-disable\-\_\-peripheral\-\_\-clock()
\item sysclk\-\_\-enable\-\_\-module()
\item sysclk\-\_\-disable\-\_\-module()
\item sysclk\-\_\-module\-\_\-is\-\_\-enabled()
\item \hyperlink{group__sysclk__group_ga9e93d93c137135fee8a1a7102367042e}{sysclk\-\_\-set\-\_\-prescalers()}
\end{DoxyItemize}

\-All other functions should be considered platform-\/specific. \-Enabling/disabling clocks to specific peripherals as well as determining the speed of these clocks should be done by calling functions provided by the driver for that peripheral.

\-Initialize the synchronous clock system. 

\-This function will initialize the system clock and its source. \-This includes\-:
\begin{DoxyItemize}
\item \-Mask all synchronous clocks except for any clocks which are essential for normal operation (for example internal memory clocks).
\item \-Set up the system clock prescalers as specified by the application's configuration file.
\item \-Enable the clock source specified by the application's configuration file (oscillator or \-P\-L\-L) and wait for it to become stable.
\item \-Set the main system clock source to the clock specified by the application's configuration file.
\end{DoxyItemize}

\-Since all non-\/essential peripheral clocks are initially disabled, it is the responsibility of the peripheral driver to re-\/enable any clocks that are needed for normal operation. \hypertarget{group__sysclk__group_ga9d3035baba081035de71adb2dd059ce7}{
